We Keep Coding

I am not able to get any of my JSLink working. What am I doing wrong

We have SharePoint 2013 on Prem and I am trying to do some customizations using JS Link. Even the most simple exercises are not working. I don't understand what I'm doing wrong.
New page - List added and jS Link = ~site/SiteAssets/js-test/OverRideCustomHeader.js
(function () {
var overrideContext = {};
overrideContext.Templates = {};
overrideContext.Templates.Header = overrideCustomHeader;
overrideContext.Templates.Footer = overrideCustomFooter;
SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideContext);
})();
function overrideCustomHeader() {
return “<h3>Our Custom Header</h3>”;
}
function overrideCustomFooter() {
return “<h3>Our Custom Footer</h3>”;
}
I expect to see a header and a footer display and they are not.

Insert script editor webpart into the page and insert the script into script editor webpart(use correct 【"】).
(function () {
var overrideContext = {};
overrideContext.Templates = {};
overrideContext.Templates.Header = overrideCustomHeader;
overrideContext.Templates.Footer = overrideCustomFooter;
SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideContext);
})();
function overrideCustomHeader() {
return "<h3>Our Custom Header</h3>";
}
function overrideCustomFooter() {
return "<h3>Our Custom Footer</h3>";
}
Update:
Have you enabled Minimal Download Strategy?
JSLink won't work if url like /_layouts/15/start.aspx# , you could disable the feature.

Vis.js: Adding showPopup in react style

I have a question to ask regarding vis.js popup option. Currently I am trying to implement it in react style so I was using https://github.com/crubier/react-graph-vis/tree/master/example as a starting point.
I realized that in src\index.js file I can add events array since I realize the select option is in there. However, when I do the following:
const events = {
select: function(event) {
var { nodes, edges } = event;
console.log("Selected nodes:");
console.log(nodes);
console.log("Selected edges:");
console.log(edges);
},
showPopup: function(event) {
document.getElementById('root').innerHTML = '<h2>showPopup event</h2>'+ JSON.stringify(params, null, 4);
}
};
I am not able to trigger the popup even at all. Inside the lib\index.js, I noticed that the code is supposed to loop over the events array:
var _iteratorNormalCompletion2 = true;
var _didIteratorError2 = false;
var _iteratorError2 = undefined;
try {
for (var _iterator2 = Object.keys(events)[Symbol.iterator](), _step2; !(_iteratorNormalCompletion2 = (_step2 = _iterator2.next()).done); _iteratorNormalCompletion2 = true) {
var _eventName = _step2.value;
this.Network.on(_eventName, events[_eventName]);
}
} catch (err) {
_didIteratorError2 = true;
_iteratorError2 = err;
} finally {
try {
if (!_iteratorNormalCompletion2 && _iterator2.return) {
_iterator2.return();
}
} finally {
if (_didIteratorError2) {
throw _iteratorError2;
}
}
}
}
and I checked that vis.js has the popup option according to the documentation which can be found here: http://visjs.org/docs/network/
I am currently stuck on figuring out how to trigger the popup. There is a requirement to use react since the application will be based on it. It would be great if someone can point out what I did wrong.
Thanks in advance. XD
NOTE: This question is in regards to the github project that I am trying to build on top of. Therefore it is a little different because I am not taking a barebone vis.js

You are mixing things up. showPopup is an event, a function that is called when the popup is shown. You do not call it to show the popup.
To show the popup you simply hover over a node that has a title property.
Check out this fiddle I made (is in pure JS though): http://jsfiddle.net/56t9c0t4/

Disable Touch on Materialize Carousel

It looks like no one has asked this question before since I've pretty much scoured the internet looking for a very simple answer.
How would one go about disabling the ability to swipe left/right on the materialize carousel?

in Materialize.js add/edit:
var allowCarouselDrag = true;
value: function _handleCarouselDrag(e) {
if(allowCarouselDrag){
....
}
}
You can set the allowCarouselDrag variable per application.

I solved it like this
// Create carouser
$('#carousel').carousel({
fullWidth: true,
indicators: false,
duration: 100,
});
// Get instance of carousel
carouselInstance = M.Carousel.getInstance(sliderDOM);
// Remove event listeners added by Materialize for corousel
document.getElementById("carousel").removeEventListener('mousedown', carouselInstance._handleCarouselTapBound);
document.getElementById("carousel").removeEventListener('mousemove', carouselInstance._handleCarouselDragBound);
document.getElementById("carousel").removeEventListener('mouseup', carouselInstance._handleCarouselReleaseBound);
document.getElementById("carousel").removeEventListener('mouseleave', carouselInstance._handleCarouselReleaseBound);
document.getElementById("carousel").removeEventListener('click', carouselInstance._handleCarouselClickBound);
After that drag/swipe is disabled and you can still change page/item via
carouselInstance.set(0);
and
carouselInstance.next(0);

This is far from a perfect solution, and it might disable too much of the functionality in your case, I'm not sure. An option to turn this on/off would be much appreciated.
But for my needs, turning off the events on the carousel did the job:
var carousel = $('.carousel.carousel-slider').carousel();
// Disable all swipping on carousel
if (typeof window.ontouchstart !== 'undefined') {
carousel.off('touchstart.carousel');
}
carousel.off('mousedown.carousel');

function tap(e) {
pressed = true;
dragged = false;
vertical_dragged = true;
reference = xpos(e);
referenceY = ypos(e);
velocity = amplitude = 0;
frame = offset;
timestamp = Date.now();
clearInterval(ticker);
ticker = setInterval(track, 100);
}

I have attempted to solve this problem for the past ~three days and have come to the conclusion that there is no clean solution other than directly editing the materialize.js file as in Lester's answer. Unfortunately, this is not an ideal solution as it causes issues when updating Materialize etc.
The simplest solution that I have come up with after this time is the following piece of javascript:
window.onload = function() {
window.mouseDownNow = false;
// The selector below must be more specific than .carousel.carousel-slider in
// order for the event to be cancelled properly.
$('.class-added-to-block-swiping-functionality')
.mousedown(function() {
window.mouseDownNow = true;
})
.mousemove(function(event) {
if(window.mouseDownNow) {
event.stopPropagation();
}
})
.mouseup(function() {
window.mouseDownNow = false;
});
};
This will simply stop the event from bubbling to the Materialize swiping functionality.
Note: I am not sure how specific the selector must be, mine were classes that were specific to text areas.

Jscrollpane and internal anchor links

I am using Jscrollpane and everything works great, except when I try to use it with an internal anchor.
It should work like the example on the official page.
But in my example it really destroys my site. The whole content is floating upwards and I can't figure it out myself.
Here is my page: http://kunden.kunstrasen.at/htmltriest/index.php?site=dieanreise&user_lang=de
and if the inner anchor is clicked: http://kunden.kunstrasen.at/htmltriest/index.php?site=dieanreise&user_lang=de#westautobahn
Anybody a clou whats going on here?
Thanks for your help.

jspane does not work with old style anchors
e.g.
<a name="anchor"></a>
instead you have to write
<a id="anchor"></a>
additionaly you have to enable
hijackInternalLinks: true;
in jScrollPane settings Object.
The hijackInternalLinks also captures links from outside the scrollpane, if you only need internal links you can add this code, like hijackInternalLinks it binds the click funktion on the a elements and calls the scrollToElement with the target:
\$(document).ready(function() {
panes = \$(".scroll");
//hijackInternalLinks: true;
panes.jScrollPane({
});
panes.each(function(i,obj){
var pane = \$(obj);
var api = pane.data('jsp');
var links = pane.find("a");
links.bind('click', function() {
var uriParts = this.href.split('#');
if (uriParts.length == 2) {
var target = '#' + uriParts[1];
try{
api.scrollToElement(target, true);
}catch(e){
alert(e);
}
return false;
}
});
});
});
but note you will always have to use the id attribute on a tags.
If you are using tinymce you can repair the code with this function
function myCustomCleanup(type, value) {
switch (type) {
case "get_from_editor_dom":
var as = value.getElementsByTagName("a");
for(var i=0; i< as.length;i++){
if (as[i].hasAttribute('name')){
var name = as[i].getAttribute('name');
as[i].setAttribute('id',name);
}
}
break;
}
return value;
}

Dashcode webapp flickers upon transition, only in iPhone Safari

I created a simple RSS web app using the template in Dashcode. Problem is, when choosing items in the list from the feed the transition flickers (even with the default settings). I am guessing its because of the images in the posts.
I tried disabling the transitions completely but even then I get a flickering when returning to the list. This problem does not appear to affect safari on OSX only on the iphone.
Here is the code that I think is responsible:
var topStories = parseInt(attributes.topStories, 30);
function load()
{
dashcode.setupParts();
// set today's date
var todaysDate = document.getElementById("todaysDate");
todaysDate.innerText = createDateStr(new Date()).toUpperCase();
setupFilters("headlineList");
// This message checks for common errors with the RSS feed or setup.
// The handler will hide the split view and display the error message.
handleCommonErrors(attributes.dataSource,
function(errorMessage) {
var stackLayout = document.getElementById("StackLayout")
if (stackLayout) {
stackLayout.style.display = 'none';
}
showError(errorMessage);
});
// get notifications from the stack layout when the transition ends
document.getElementById("StackLayout").object.endTransitionCallback = function(stackLayout, oldView, newView) {
// clear selection of lists when navigating to the first view
var firstView = stackLayout.getAllViews()[0];
if (newView == firstView) {
document.getElementById("headlineList").object.clearSelection(true);
}
}
}
function articleClicked(event)
{
document.getElementById("StackLayout").object.setCurrentView("articlePage", false, true);
}
function backToArticlesClicked(event)
{
document.getElementById("StackLayout").object.setCurrentView("frontPage", true);
}
function readMoreClicked(event)
{
var headlineList = dashcode.getDataSource('headlineList');
var secondHeadlines = dashcode.getDataSource("secondHeadlines");
var selectedItem = null;
if (headlineList.hasSelection()) {
selectedItem = headlineList.selectedObjects()[0];
} else if (secondHeadlines.hasSelection()) {
selectedItem = secondHeadlines.selectedObjects()[0];
}
if (selectedItem) {
var link = selectedItem.valueForKeyPath('link');
// If the link is an object, not a string, then this may be an ATOM feed, grab the actual
// href from the href attr
if (typeof(link) == 'object') {
link = selectedItem.valueForKeyPath('link.$href');
// If the link is an array (there is more then one link), just grab the first one
if (DC.typeOf(link) == 'array') {
link = link[0];
}
}
window.location = link;
}
}
var headlineListDataSource = {
// The List calls this method once for every row.
prepareRow: function(rowElement, rowIndex, templateElements) {
if (rowIndex >= topStories) {
templateElements['headlineDescription'].style.display = 'none';
templateElements['headlineTitle'].style.fontSize = '15px';
}
}
};

The following CSS rule fixed all of my "-webkit-transition" animation flickering issues on the iPad:
body {-webkit-transform:translate3d(0,0,0);}

I am not sure how well that applies to your problem but in general you should set the backface visibility to hidden if not needed. That will most likely kill all flickering on a page.
-webkit-backface-visibility: hidden;
